The turquoise waters surrounding Fraser Island are a frenzy of sea life. The world’s largest sand island is a spectrum of vibrant greens, and the World-Heritage-listed sand bar is simply stunning and the perfect spot for beach fishing. There aren’t paved roads here, just sand tracks, making the entirety of Fraser Island one big 4WD, off-roading adventure.

The pink sands of Champagne Beach spill into warm waters filled with wrecks and reefs begging to be explored by Espiritu Santo holiday-makers. Rinse off with a dip in one of the island’s many freshwater blue holes. Trek over a bamboo bridge to visit the bats and swallows of Millennium Cave, who nap among spectacular rock formations. Divers can wave hello to “The Lady,” one of the many intact artifacts of the wreck of the SS President Coolidge.

Seminyak boasts some of the most glorious beaches in Bali. Be sure to catch the legendary sunsets and enjoy the tranquil beauty, and marvel at Balinese ceremonies on the beach, complete with gamelan players and offerings to the gods. Of course, don’t let the smooth sands and intricate cultural experiences distract you from spas and shopping! Sophisticated spas and high-end boutiques will entice you away from the waterfront—for a short time, anyway.

Bali is a living postcard, an Indonesian paradise that feels like a fantasy. Soak up the sun on a stretch of fine white sand, or commune with the tropical creatures as you dive along coral ridges or the colorful wreck of a WWII war ship. On shore, the lush jungle shelters stone temples and mischievous monkeys. The “artistic capital” of Ubud is the perfect place to see a cultural dance performance, take a batik or silver-smithing workshop, or invigorate your mind and body in a yoga class.

Vietnam's bustling largest city sets the cultural and economic pace for the country. The former Saigon boasts charming French colonial architecture and wide boulevards, usually thronged and choked with traffic. Taxis are an option for seeing the sprawling city. The War Remnants Museum shows the Vietnam War through Vietnamese eyes. Don't miss the impressive Jade Emperor Pagoda. Go to the frenetic Ben Thanh Market for food, flowers or frogs. Tour through the Mekong Delta, past rice paddies and houseboats.

Tradition collides with pop culture in Tokyo, where you can reverently wander ancient temples before rocking out at a karaoke bar. Wake up before the sun to catch the lively fish auction at the Toyosu Market, then refresh with a walk beneath the cherry blossom trees that line the Sumida River. Spend some time in the beautiful East Gardens of the Imperial Palace, then brush up on your Japanese history at the Edo-Tokyo Museum. Don’t forget to eat as much sushi, udon noodles, and wagashi (Japanese sweets) as your belly can handle.
